These filters, manufactured from the finest solid optical glass, are ground
and polished to the most practical thinness. In addition they are heat-treated
to avoid any distortion or focal shift, and each filter is subject to strict
tests in order to ensure a perfect even surface which is essential to a good
filter.

Name

Colors

Factor

UV

Transparent

Absorbs
ultra-violet rays without increase of exposure, thereby preventing
haziness and foggy effects in distant landscape. It creates clearness.
Constant use of this filter is recommended for clearer pictures as well
as a lens protector.

Skylight

Light Pink

Creates the
effects given by Y2 filter in case of black and white film. Reduces
excess blue and adds warmth to the pictures. All purpose filter.

Polarizing (PL)

Gray

Removes or
reduces reflections from non-metallic surfaces, darkens blue sky while
increasing color saturation penetrates haze. Simply rotates the filter
in its mount until the optimum effect is obtained.

Cicular Polarizing (C-PL)

Gray

It is similar
to the ordinary polarizing filter, except rays go circular, no
linear, after passing through the circular polarizing filter. It
eliminates possible exposure errors which may be caused by the slight
polarizing of rays in cameras of the TTL system using fixed mirrors.
